| 摘 要： | 通过深入研究二把伙银矿床的成矿地质背景、成矿作用及银矿化富集特征,结果认为,矿区发育在一个燕山（晚）期层状火山岩中叠加的岩浆穹隆的复式火山机构中。该火山机构及其后期断裂构造共同控制了二把伙银矿的形成。成矿后局部地段发生了明显的次生富集作用,由此而形成富银矿石。

| Abstract: | An in-depth study Was carried on for the ore forming geological background, mineralization process and silver enrichment characteristics of the Erbahuo silver deposit. It was concluded that the deposit occurs in a superimposed compound volcanic mechanism in magmatic dome in Late Yanshanian Period. The volcanic mechanism and its succeeding fracture structure jointly controlled the formation of the Erbahuo silver deposit. Some obvious secondary enrichment occurs in part after primary mineralization, forming bonanza silver ores. |
